You can make more than one shipment for a sales order before posting and printing an invoice. In such a case, the system assumes there is only one pending invoice, and that quantities for the successive shipments are to be added until the invoice is posted. To separate invoices for each shipment, post and print the pending invoice after each shipment and before the next. If there is another shipment before the pending invoice is posted, the system prompts you to either delay the next shipment or post the outstanding pending invoice.

Optionally, the system can cross-reference shipper numbers to printed invoices. The Print Shipper Number on Invoices field in Sales Order Accounting Control (36.9.6) controls this feature.
